UNITED STATES PATENT OFFICE.

GEORGE J. coLBY, OF WATEEB'UEY, VERMONT.

IMPROVED FLOORING OR DUST-RACK FOR CARPETS.

T 0 all whom it may concern:

lie it known that I, GEORGE J..()oI.EY, of thetown of \vaterbury, in the county of Washington, in the State ot'Vermont, have invented anew and useful lortable Open Flooring or Dust-Rack to Place under Carpets, and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 shows a top- View of the article. Fig. 2 is an end view of the same.

The object of my invention is to let the dust through the carpet when sweeping or moving about on it, to prevent its rising and lodging on the furniture in the room and affecting the lungs, and the annoyance of dust generally in the room.

Myinvention consists in making frame-work of an inch in thickness, in sections of one yard (more orless) square, to be placed on the door of a room under a carpet, the slats being beveled off on the under side so as to leave openings between each of them, the cracks or openings being quite narrow on the surface, but wide underneath, so as to form a receptacle for the dust or whatever else may pass through the fabric when it finds a lodgment. The carpet, being fastened to the end sections of the slat-frames, may be easily rolled or folded over from each way and the dust removed as often as desired.

To enable others skilled in the art to make and use my invention, I will describe it more fully, referring to the drawiugs,and to the letters marked thereon.

I use good hard, smooth wood, which I cut up into slats A. AAA, they being beveled oft, so that when secured together by cross-ties B B thespace undereach crack or opening a a a a will be considerably enlarged, making room for the dust to be secreted. The slats or crossties B B may be dovetailed and driven into the slats A A A A; or they may be simply notched and secured together by nails or brads, the cracks or openings to a a a at the top not being more than an eighth of an inch in width, the corners sharp by being beveled under on both sides, so that in the spaces 1) b b b b betweenthe slats there is ample room for the dust to be deposited, where it will remain undisturbed till the sections of the open flooring are taken up to remove it.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, i.s

A portable fioorin g to be laid under carpets,

the same being made of beveled slats secured together in sections, with suitable openings to allow the dirt and dust to pass through, as

herein specified.
